FUEL-HEATER FOR EXPLOSIVE-ENGINES.

Specification of Letters Patent.

Patented June 1'7, 1919.

Application filed August 13, 1917. Serial No. 186,068.

To all whom it may concern:

Be it known that I, GEORGE H. HAYES, a citizen of the United States,residin at Hazelton, in the county of Barber and tate of Kansas, haveinvented a certain new and useful Improvement in F uel-I-Ieaters forExplosive-Engines, of which the following is a specification.

My invention relates to improvements in fuel heaters for explosiveengines.

The object of my invention is to provide novel means for supplyingheated fuel to an explosive engine, so that the engine may be easily andquickly started in cold weather.

The novel features of my invention are hereinafter fully described andclaimed.

In the accompanying drawing which illustrates the preferred embodimentof my invention,

Figure 1 is an elevation, partly broken away, of an ordinary carbureterand manifold provided with my improvement.

Fig. 2 is an enlarged vertical sectional view of the fuel container ofthe heater, a portion of the fuel conductor heated thereby being shownin elevation.

Fig. 3 is a top view of what is shown in gimilar reference charactersdesignate similar parts in the different views.

1 designates an ordinary carbureter which discharges into the intake endof a common manifold such as is employed on explosive engines.

3 designates a liquid fuel conductor having a branch 4 leading to thecarbureter and provided with a branch 5 which discharges into the intakeportion of the manifold 2.

In the branch 5 is provided a shut-off valve 6.

For heatin the liquid fuel before it enters the carbureter,independently of the engine with which the carbureter may be connected,the branch 5 is provided with a coiled portion 7, preferably locatedbelow the manifold 2 and disposedin a fuel container, preferablycomprising a cup 8, which is supported by a clip 9 which embraces thebranch 5. I

The' upper portion of the side walls of the container-' 8 may beprovided with perforations 10 for admitting? air to support combustionof the fuel held within the container.

In the operation of my invention, fuel, such as gasolene, is poured intothe container 8 and lighted, after which the shutoff valve 6 is opened,thus permitting fuel to pass through the branch 5 into the manifold 2.The burning fuel in the container 8 heats the coiled portion 7 and themanifold 2, thereby heating the fuel, such as gasolene, which passesthrough the branch 5 into the manifold. The engine may be readilystarted with the heated fuel, following which the shut-off valve 6 isclosed, and the manifold is thereafter supplied with the explosivemixture which is discharged from the carbureter 1 into the manifold 2.

I do not limit my invention to the structure shoWn and described, asmodifications, within the scope of the appended claims, may be madewithout departing from the spirit of my invention.

What I claim is 1. A carbureter, a manifold connected therewith, aliquid fuel conductor having two branches respectively discharging intothe carbureter and into the manifold, a shutoff valve in the branchleading to the manifold, and means independent of an engine to which thecarbureter may be connected for heatin the branch which leads to themanifold.

2. A carbureter, a manifold connected therewith, a liquid fuel conductorhaving tWo branches respectively discharging into the carbureter andinto the manifold, a shut-off valve in the branch connected with themanifold, and a fuel container located so that heat from burning fuelcontained therein will heat the branch leading to the manifold.

3. A carbureter, a manifold connected therewith, a liquid fuel conductorhaving two branches respectively discharging into the carbureter andinto the manifold, a shutoff valve in the branch connected with themanifold, the branch connected with the manifold having a coiledportion, and a container for liquid fuel in which said coiled portion islocated.

4. A carbureter, a manifold connected therewith, a container adapted: toholdburn 5. A carbureter, a manifold connected therewith, aliquid fuelconductorhavingtwo branches respectively discharging into the carbureterand into the manifold; the branch connected with the manifold beingprovided with a shut-01f valve and having a coiled portion, and acontainer for liquid fuel hav- 10 ing an open top and encircling saidcoiled portion.

In testimony whereof I: have signed my name to this specification.

GEORGE H. HAYES.
